My wish is that when they stop producing new packs, that they could create a few more empty worlds based on the styles we already got. I wouldn't request a fantastic or original world concept, simply an addition/expansion of earlier worlds with more residential lots. Oasis Springs II can't be that costly to produce, Selvadorada II might require some more planning and distant views, but they could base it on a remake and just adjust lot placements and trails and just enough bigger changes to the world map to let us tell a difference.
